the bottom line 

the total, sum, net profit or loss, final conclusion. When your boss starts a conversation with the bottom line because they don't want to, or can't explain why they came up with their demands.

the bottom line is that you have to do this particular job because I said so!

watching the bottom line

Carefully monitoring the "level" of your pants' waistband so as not to reveal your "plumber's crack' when working in public.

"Watching the bottom line" can also refer to a bystander's lengthy observation of someone who is unknowingly "mooning the world" while engrossed in the task he's performing. Sometimes you can gain a bit of extra folding-money if you make a bet with anyone else who's with you about how long it'll be before the clueless butt-exposer either realizes his faux pas or someone else yells at him to pull his pants up.
